The present invention relates to a flap actuation system for an aircraft, and discloses a system for actuating the flap coupled to a wing of the aircraft along a streamwise direction. The system comprises a geared rotary actuator comprising a drive gear that is rotatable about a first rotational axis. The system also comprises a crank shaft comprising a driven gear in gear meshing engagement withthe drive gear of the geared rotary actuator to rotate the crank shaft about a second rotational axis. The second rotational axis is angled relative to the first rotational axis. The system further comprises a crank arm co-rotatably coupled to the crank shaft and configured to be coupled to the flap. The rotation of the crank shaft about the second rotational axis rotates the crank arm in a direction perpendicular to the second rotational axis.
本发明涉及用于飞行器的襟翼致动系统,本文公开了一种用于沿顺气流方向致动耦接至飞行器机翼的襟翼的系统。该系统包括齿轮式旋转致动器,该齿轮式旋转致动器包括可围绕第一旋转轴线旋转的驱动齿轮。该系统还包括曲柄轴,该曲柄轴包括与齿轮式旋转致动器的驱动齿轮齿轮啮合接合的从动齿轮,以使曲柄轴绕第二旋转轴线旋转。第二旋转轴线相对于第一旋转轴线成角度。该系统还包括曲柄臂,该曲柄臂被共同可旋转地耦接至曲柄轴并且配置成耦接至襟翼。曲柄轴绕第二旋转轴线的旋转使曲柄臂沿垂直于第二旋转轴线的方向旋转。
